Hey... There is a good possibility that I will be on that ferry on Saturday about lunchtime... It'll take me about 3 hours to drive down from Dundee, up past Stirling to Drymen and Balmaha then up Loch Lomond to Arrochar and up the Rest-and-be-Thankful, down Hell's Glen to St Catherine's (I know Glen Kinglas is faster, but Hell's is nicer, and I might be tempted to go down Loch Goil to Carrick Castle) and up past Strachur to Colintraive... Or, alternatively, I might just drive down the motorway to Wemyss Bay and get the big ferry!
